How Has the Deprioritization of Rts 28 Reports Affected Best Execution Monitoring Practices in the Eu?

Concept

The operational calculus for European investment firms has been fundamentally altered. The directive from the European Securities and Markets Authority (ESMA) to deprioritize enforcement of Regulatory Technical Standard 28 (RTS 28) reports is a systemic signal. This action recalibrates the focus from a public-facing, compliance-centric reporting exercise to a more profound, internalized mandate for execution quality.

The RTS 28 framework, born from Article 27(6) of MiFID II, was architected to inject transparency into the market by requiring firms to annually disclose their top five execution venues and provide data on the quality of execution achieved. The design principle was that such disclosures would empower investors with comparable data, fostering a competitive environment where best execution is a demonstrable asset.

The evidence, however, pointed to a different reality. The reports were seldom used by the investors they were intended to help. Feedback gathered during the MiFID II review process indicated that the data was difficult to compare meaningfully and often failed to provide actionable insights for end clients.

Consequently, the European Parliament moved to delete the obligation entirely from the MiFID II framework. This decision acknowledges a core operational truth ▴ true best execution is an outcome of a firm’s internal systems, analytical capabilities, and governance, a reality that cannot be fully captured or enforced through a standardized public report.

The removal of RTS 28 reporting shifts the burden of proof for best execution from a public disclosure exercise to a matter of demonstrable internal diligence and sophisticated data analysis.

This deprioritization is a component of a larger recalibration within the MiFID II/MiFIR review. It reflects a maturation of the regulatory perspective, recognizing that prescriptive reporting can sometimes lead to a “tick-the-box” mentality. The focus now pivots toward the substantive obligation of best execution itself. ESMA has been clear that while the reporting requirement is being phased out, the core duty for firms to achieve the best possible result for their clients remains absolute and will be subject to supervision.

This creates a new operational challenge. Firms must now construct and maintain an internal framework that not only achieves superior execution but can also prove it to regulators upon inspection, without relying on the public filing of an RTS 28 report as the primary evidence.

Strategy

The strategic imperative for investment firms now transcends the simple production of a compliance document. It demands the cultivation of a dynamic, data-centric execution management system. The deprioritization of RTS 28 reports liberates resources previously allocated to report generation, allowing them to be reinvested into the systems that actually drive execution quality.

This represents a move from a static, historical reporting model to a continuous, real-time optimization framework. The core strategic adjustment is the institutionalization of a robust internal audit and analysis capability that is both proactive and evidence-based.

What Is the New Strategic Focus for Firms

The new strategic focus is on building a defensible and intelligent execution policy. This policy must be grounded in comprehensive data analysis that goes far beyond what was required for RTS 28. Firms are now incentivized to develop sophisticated Transaction Cost Analysis (TCA) as a central pillar of their strategy.

A mature TCA program provides a much richer and more granular view of execution performance than the aggregated, high-level data presented in the old reports. It allows firms to dissect the entire lifecycle of a trade, from pre-trade decision support to post-trade analysis of slippage and market impact.

Firms must now architect an internal execution intelligence framework that continuously monitors, analyzes, and optimizes performance across all venues and counterparties.

This strategic pivot requires a clear understanding of the different components that constitute a modern best execution framework. It is an integrated system of technology, data, and governance.

• Data Aggregation ▴ Firms must now source and integrate a wider array of market data. This includes not just public data from exchanges but also pre-trade liquidity indicators, data from alternative venues, and the firm’s own historical execution data. The goal is to create a proprietary data lake that can be mined for insights.
• Analytical Tooling ▴ The strategy requires investment in advanced analytical tools. These tools must be capable of performing multi-factor TCA, venue analysis, and algorithm performance measurement. The output of this analysis should directly inform the firm’s order routing and execution strategies.
• Governance and Oversight ▴ A formal governance structure is needed to oversee the best execution process. This includes a committee responsible for reviewing TCA reports, challenging execution decisions, and updating the firm’s execution policies based on empirical evidence.

Comparing the Old and New Regimes

The transition from the RTS 28 era to the new environment can be viewed as a shift in the location of the analytical burden. Previously, the framework encouraged a degree of public comparison, however flawed. Now, the analysis is an internal responsibility, with regulatory scrutiny applied to the robustness of the internal process itself.

Execution

In the post-RTS 28 environment, the execution of a best execution policy is an exercise in systemic design and continuous data-driven validation. The abstract requirement to achieve the “best possible result” must be translated into a concrete, auditable, and adaptive operational workflow. This requires a fusion of technology, quantitative analysis, and rigorous internal governance that places the analytical burden squarely within the firm.

How Do Firms Operationally Adapt to This Change?

Firms must now engineer an internal ecosystem for execution quality monitoring that is far more sophisticated than the process used to generate RTS 28 reports. The operational focus shifts from producing a static annual document for public consumption to maintaining a dynamic internal evidence base that can withstand regulatory scrutiny at any time. This involves several key operational pillars.

1. Systematic Data Capture ▴ The foundation of the new execution framework is the systematic capture of granular order and trade data. This includes timestamping (to the microsecond), order routing decisions, fill details, and pre-trade market conditions. This data must be warehoused in a structured manner that facilitates complex analysis.
2. Implementation of Advanced TCA ▴ Firms must move beyond simple average price benchmarks. A robust TCA function will analyze execution costs against multiple benchmarks (e.g. Arrival Price, VWAP, TWAP) and decompose costs into their constituent parts, such as market impact, timing risk, and spread cost. This analysis must be performed across different asset classes, order types, and venues.
3. Dynamic Venue Analysis ▴ The process of evaluating and selecting execution venues must become a continuous, data-driven process. Firms need to analyze fill rates, rejection rates, latency, and post-trade price reversion for each venue they use. This analysis allows for the dynamic adjustment of order routing logic to favor venues that consistently provide superior results for specific types of flow.
4. Formalized Governance and Review ▴ A dedicated committee or function must be established with responsibility for overseeing execution quality. This body will review TCA reports, challenge outliers, and approve changes to the firm’s execution policy and routing tables. The minutes and decisions of this committee form a critical part of the audit trail.

The operational mandate is to build a closed-loop system where execution data is captured, analyzed, and the resulting insights are fed back to refine future trading strategies.

A New Operational Blueprint

The operational blueprint for best execution monitoring has fundamentally changed. The table below outlines the practical differences in the operational tasks required in the old versus the new regime. It highlights the shift from a compliance-focused, periodic task to an integrated, continuous, and analytically demanding function.

This evolution requires a significant investment in both technology and human expertise. Firms need quantitative analysts who can design and interpret complex TCA models, data engineers who can build and maintain the required data infrastructure, and experienced traders and compliance officers who can provide effective oversight. The ultimate goal is to create a self-improving system where every trade generates data that helps the firm execute the next trade better.

Reflection

The phasing out of the RTS 28 reporting mandate presents a critical moment of introspection for every investment firm. It compels a shift in perspective, moving the concept of best execution from the domain of regulatory compliance to the core of a firm’s operational identity and competitive strategy. The essential question now becomes internal ▴ Is our execution framework merely sufficient to avoid sanction, or is it engineered to deliver a superior, quantifiable, and defensible outcome for our clients?

The absence of a public reporting standard creates a vacuum that can only be filled by a firm’s own commitment to analytical rigor and continuous improvement. This is an opportunity to build a proprietary execution intelligence system that becomes a genuine source of alpha, a system where the quality of execution is not an afterthought documented for regulators, but the primary output of a sophisticated and well-governed operational architecture.
